聚乙二醇6000双硬脂酸酯(DM-638)
Polyethylene Glycol 6000
Distearate
DM-638
Polyethylene Glycol 6000 distearate is a kind of nonionic surface active
agents. It could solve in water, Ethanol or other solvent. Presently, it is
widely used in shampoo, body wash, facial washing milk and other liquid wash as
a thickener. And it also can be used as cosmetics emulsifier. In addition, it
is a widely used industrial emulsifier in the area of coating and textiles.
聚乙二醇6000双硬脂酸酯是一种高分子的非离子表面活性剂，加热后可溶解于水、乙醇等溶剂中。
目前，已经广泛应用于香波、沐浴液、洗面奶等液体洗涤剂的增稠，同时可用作化妆品的乳化剂。另外， 聚乙二醇6000双硬脂酸酯还是一种应用非常广泛的工业用乳化剂，应用在涂料、纺织印染等领域。

Handling（使用方法）
1、Add DM-638, AES, 6501 in
proportion, heat to 70~75℃, stir sufficiently to solve.
方法一：将 DM-638 按比例与 AES、6501 等表面活性剂一块加热至 70~75℃，充分搅拌， 溶解即可。
2、Make 10~20% water solvent, (add DM-638 in
cold water, slowly heat to 70~75℃, stir
sufficiently to solve,) cool to 40~50℃, and
add this water solution into the ready product.
方法二：先将 DM-638 配成 10~20%的水溶液（最好投入冷水，再缓慢加热至 70~75℃， 充分搅拌、溶解），再按比例于 45~50℃时加入已配好的产品中。
3、Usage
concentration of 0.2~2.0% (by weight). 建议添加量：0.2~2.0%
